I think I remember reading somewhere that geomancy was forbidden in Islam, but I can’t recall where I read it. Just now, however, I was reading about Daniel from a Jewish source. It mentioned that Muslims attribute this form of divination to him, as well as the book Usul al-Ta’bir.
Wow. The book in question is online.

Your answer had what I was looking for, but 1672 was the only bit I needed.
